WINDOW.

To all whom it may concern:

Be it known that I, EDMUND H. LUNKEN, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Windows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

' My invention relates to what is known as pocket windows in which a pocket is provided in the upper portion of the sash frame for the reception of the sash to give a free and unobstructed window opening. It is usual in pocket windows of the kind speciied to also provide for window screens which are located outside the sash and adapted to be also pushed up into the window pocket to obtain free access to the sash.

My invention in this connection has particularly to do with pocket windows in.

which by reason of the height of the framework, or for any-other cause, it is not practicable to provide a pocket to receive the full length of the sash. The invention also has relation to a construction in which pro-v vision shall be made in the sash frame for window screens, but in which the screens if desired mav be omitted or removed without expos-ing an air opening around the sash. It is the object, therefore, of my present invention to arrange a construction in which the'pockets for the window sash and for the screens shall be entirely independent of each other and s0 that whether screens are used or not, no air opening shall exist around the sash by reason of the pocket construction.

The invention consists of that novel construction and arrangement of parts to be hereinafter specifically pointed out and claimed whereby this independence of the sash and screen pockets shall be obtained.

In the drawing,

Figure 1 is a vertical longitudinal section taken through a window embodying my invention, with the screens in place closing the window opening.

Fig. 2-is a similar longitudinal section of the upper portion of the window showing the screens raised into the window pocket.`

Fig. 3 is a cross section of the window frame taken on the lines 3-3 of Fig. 1.

The window pocket is provided with the usual lower and upper sliding sashes 1 and education of Letters Patent.

2, with the meeting rails 3, 4, the sashes being mounted in the side stiles 5, 6, with the inside and outside beads `7, .8, and the part-y 1ng bead 9, with the sill 10 and head piece 11. The stiles run to the top of the pocket above'the window opening and the head piece incloses the pocket at the top, while the front of the pocket is in the construction illustrated formed of corrugated sheet metal 12 for the plastering 13, and the outer wall ofthe pocket is inclosed by sheeting 14 over which the weatherboarding 15 for the outside structure in frame buildings is secured. The window casing is also provided with the usual inside and outside trims 16, 17. The' wall pocket, which in the construction illustrated is say, of only three-quarters depth, is divided by the partition 18 into two independent pockets, front and rear, of a sufficient horizontal depth to receive the two sashes and two screens respectively. These screens are preferably formedpf metal frames 19 for the lower, and 2O for the upper screen, with the wire screening 21 secured to the frames in any suitable way.v The lower screen is provided with a flanged strip 22 to engage over the lower rail of the upper screen, to form a close joint and to raise the upper screen when the two screens are pushed up into the pocket, while the upper rail of the upper screen is provided of double thickness as shown at Q3 to ll out the opening in the guide way.

The partition 18 completely divides the pocket, and the lower edge of the partition extends to the upper portion of the window opening, and this lower edge is provided with a U-shaped preferably metallic binding piece 24, which surface forms a contact piece for the weatherstrip 25, which is secured along the upper rail of the upper sash, and thus forms a tight weatherproof joint for the sash, and prevents the entrance of air around the sash through the window pocket. In addition this binding strip for the partition gives sufficient space between the partition and the parting bead for raising the upper sash into the pocket without binding.

To serve as a suitable runway and guide for the screens, I provide the U-shaped channel pieces 26, which are mounted on the side stiles and run from the bottom to the head of the pocket, and the upper rails of the ico4 irre screens lieve lilieir side fece-s soinewliei; curved so as to provide en easy sliding contact in diese guide channels, and et die seine time sui'iicienl; rricrionel connect izo maintain rlie screens in raised position The lower rail of lie lower screen freine is also provided with :in angle plete 27, ifne ends of u'nicli are guided in ille side channels,

The sashes ere provided with elle usuel sash cords 28, which run over the sash nnln.

leys Q9 et tlie heed of the pulley stile ai; the upper end orn the pocket, end diese cords :irc attached ro the usual sash Weights 30 in the weight loos 3l behind rlie Stiles.

lilith this construction of poclrei Window, with the sash and screen poclrers independcnr, it is evidenc inet Jdie screens can be removed or entirely dispensed Wish, Wienour in any Weyadeciing ine uiliy of the sash pocket construction. A eight tting weatherproof joint is provided for the Wectherstrip on the upper surface or the upper rail of the upper sasli. Secured in ille screen channel by rivers or screws are spring plaies or strips 32 which beer against the sides of the screens end spring out to hold rlie screens up when raised beyond elle ends of the plates and Wliiclri ere pressed in to release the screens. Tlie upper screen is held in iis lowered posiion by sirniler springs 33 which engage s norcia in the upper side edges of the screen ireine on e cli side.
